EMBODIMENT

[0024] The embodiment of the application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the application, but cannot be used to limit the scope of the application.

[0025] As Figures 1-2As shown, the present application provides technical solutions: a kind of intelligent simulation combat training robot, including upper body transmission box 1 and eye sensor 4, the top of upper body transmission box 1 is fixed with head connecting spring 2, and the top of head connecting spring 2 is fixed with head 3, eye sensor 4 is embedded in the surface of head 3, the upper part of the both sides of upper body transmission box 1 is rotatably connected with arm connecting shaft 5 by bearing, and the one end of arm connecting shaft 5 is connected with simulation arm 6, the other end of arm connecting shaft 5 is rotatably connected with arm transmission rod 7, and the outer wall of the other end of arm connecting shaft 5 is connected with arm force storage disc spring 8, the bottom of arm transmission rod 7 is connected with arm transmission runner 9, and the side of arm transmission runner 9 is connected with arm transmission motor 10, the output shaft outer wall of arm transmission motor 10 is provided with arm transmission one-way bearing 30, head 3 is elastically connected with upper body transmission box 1 by head connecting spring 2, and the side of arm force storage disc spring 8 is connected with upper body transmission box 1;

[0026] Specific operation is as follows, in initial state, arm transmission one-way bearing 30 one-wayly clamps the output shaft of arm transmission motor 10, so that arm transmission runner 9 is pressed against arm transmission rod 7, so that arm force storage disc spring 8 is in the state of energy storage, and the weight of simulation arm 6 is supported to be in the state of lifting, then when using the intelligent simulation combat training robot, two arm transmission motors 10 rotate 180 degrees to drive arm transmission runner 9 to make arm connecting shaft 5 rotate 30 degrees, arm connecting shaft 5 rotates again to store energy for arm force storage disc spring 8, so that two simulation arms 6 are put down, and at this time, arm transmission motor 10 is powered off and in the state of static, and still using arm transmission one-way bearing 30 one-wayly clamps the output shaft of arm transmission motor 10, so that arm transmission runner 9 is pressed against arm transmission rod 7, so that arm force storage disc spring 8 is in the state of energy storage, at this time, intelligent simulation combat training robot enters intelligent interactive defense mode;

[0027] The eye sensor 4 and the sensor in the trainer's wearing device transmit signals to the main control board. Specifically, the trainer wears a training glove, which is internally provided with a spatial positioning sensor for capturing the trajectory of the fist. The eye sensor 4 and the glove with the sensor are used together. At the same time, since the trainer often uses not only the fist to attack, but also other attack parts of the trainer, the corresponding sensor-equipped protective gear is also worn to capture the running trajectory of each attack part of the trainer. When the main control board detects that the left and right sides are about to be attacked, the corresponding side arm transmission motor 10 is controlled to rotate once and stop quickly, so that the arm transmission rotating wheel 9 no longer pushes against the arm transmission rod 7, so that the arm force storage spring 8 releases the force storage state, and the corresponding side simulated arm 6 is instantly lifted through the arm connecting shaft 5, thereby preventing the upcoming attack on that side. When the main control board detects that the attack has stopped, the arm transmission motor 10 rotates again by 180 degrees, so that the arm force storage spring 8 again enters the force storage state, and the simulated arm 6 again enters the lowered state. At the same time, the arm transmission motor 10 is powered off and in a stationary state, and the arm transmission one-way bearing 30 is used to one-wayly clamp the output shaft of the arm transmission motor 10, and waits for the next imminent attack to quickly make a defensive action.

[0028] As shown in Figure 1 、 Figure 3 , the inner wall of the upper body transmission box 1 is connected to the waist connecting support 11 through a bearing in the middle, and the waist connecting support 11 is internally provided with a waist transmission motor 12. The bottom output shaft of the waist transmission motor 12 is connected to the waist transmission sprocket 13 through a vertically distributed and meshing conical gear set. The bottom of the waist connecting support 11 is provided with a waist converter 14, and the inside of the waist converter 14 is provided with a converter sprocket 15. The surface of the converter sprocket 15 is meshed with the waist transmission chain 16 of the waist transmission sprocket 13. The side surface of the converter sprocket 15 is meshed with the converter shaft 17, and the two ends of the converter shaft 17 are externally slidably connected to the simulated leg 18. The top of the simulated leg 18 is connected to the bottom of the waist connecting support 11 on both sides. The two sides of the waist transmission motor 12 are provided with an upper body transmission sprocket 19, and the surfaces of the upper body transmission sprocket 19 and the waist transmission sprocket 13 are provided with an upper body transmission chain 20. The upper body transmission chain 20 and the waist transmission chain 16 are distributed in front of and behind the waist transmission sprocket 13, and the two ends of the upper body transmission chain 20 are connected to the bottom of the upper body transmission box 1 on both sides.

[0029] The specific operation is as follows: when the main control board detects that the upcoming attack also includes a frontal attack, for example, when the main control board detects that the upper body transmission box 1 is about to be attacked on the front and left side, the main control board controls the left side of the simulated arm 6 to lift up, at the same time, the waist transmission motor 12 drives the waist transmission sprocket 13 to rotate, and through the waist transmission chain 16, the waist transmission sprocket 13 drives the transmission sprocket 15 inside the waist transmission chain 16 to rotate, so that the transmission shaft 17 slides to the left inside the simulated leg 18, at the same time, the rotation of the waist transmission sprocket 13 also drives the upper body transmission chain 20 to transmit, so that the upper body transmission chain 20 pulls the upper body transmission box 1 to the right to incline, when the main control board detects that the attack stops, the waist transmission motor 12 rotates to reset the upper body transmission chain 20, so that the upper body transmission box 1 restores to the upright sleeve to prepare for the next attack;

[0030] When the main control board detects that the upper body transmission box 1 is about to be attacked on the front and right side, the main control board controls the right side of the simulated arm 6 to lift up, at the same time, the waist transmission motor 12 drives the waist transmission sprocket 13 to rotate, and through the waist transmission chain 16, the waist transmission sprocket 13 drives the transmission sprocket 15 inside the waist transmission chain 16 to rotate, so that the transmission shaft 17 slides to the right inside the simulated leg 18, at the same time, the rotation of the waist transmission sprocket 13 also drives the upper body transmission chain 20 to transmit, so that the upper body transmission chain 20 pulls the upper body transmission box 1 to the left to incline, when the main control board detects that the attack stops, the waist transmission motor 12 rotates to reset the upper body transmission chain 20, so that the upper body transmission box 1 restores to the upright sleeve to prepare for the next attack;

[0031] Therefore, the intelligent simulation combat training robot can simulate the human body state when a real person is hit, so that the intelligent simulation combat training robot is closer to the real person's reaction, thereby improving the immersion of combat training.

[0032] As shown in Figure 1 , Figures 4-5 , the bottom of the simulated leg 18 is connected with a base support 21 through a bearing, one side of the bottom of the base support 21 is provided with a base connecting spring 22, the other side of the bottom of the base support 21 is provided with a rear end connecting spring 23, the bottom of the base connecting spring 22 is connected with a ground base 24, the bottom of the base support 21 is also fixed with a front end connecting wheel 25, the front end connecting wheel 25 is located on the side of the base connecting spring 22, the surface of the ground base 24 is fixed with a backward driving motor 26, the output shaft of the backward driving motor 26 is engaged with a motor sliding shaft 27, one end of the motor sliding shaft 27 is connected with a rear end connecting wheel 28, the other end of the motor sliding shaft 27 is connected with a front end backward wheel 29, the surface of the one end of the motor sliding shaft 27 close to the rear end connecting wheel 28 is connected with the bottom of the rear end connecting spring 23;

[0033] The specific operation is as follows: the initial state of the intelligent simulation combat training robot is the upright mode, when the training mode is started and the main control board detects that a frontal attack is about to be received, the backward driving motor 26 drives the motor sliding shaft 27 to move forward, that is, to move to the direction of the front end connecting wheel 25, so that the front end backward wheel 29 lifts the front end connecting wheel 25, at the same time, the other end of the motor sliding shaft 27 drives the rear end connecting wheel 28 and the bottom of the rear end connecting spring 23 to move forward, at this time, the rear end connecting spring 23 is bent and the rear end of the base support 21 is pressed down, while the base connecting spring 22 is stretched and bent because the front end connecting wheel 25 is lifted, so that the front end of the base support 21 is lifted, so that the intelligent simulation combat training robot enters the backward state when it is hit, and after the main control board detects that the intelligent simulation combat training robot is backward at a preset angle, the backward driving motor 26 is reversed to make the intelligent simulation combat training robot return to the upright state to meet the next attack.

[0034] In summary, as shown in the drawings, the intelligent simulation combat training robot, when in use, first uses the one-way nature of the arm driving one-way bearing 30 to block the output shaft of the arm driving motor 10 in the initial state, so that the arm driving rotating wheel 9 is pressed against the arm driving rod 7, so that the arm force storage disc spring 8 is in the force storage state, and the weight of the simulation arm 6 is lifted to the lifted state; Figures 1-5 Then, when using the intelligent simulation combat training robot, the two arm driving motors 10 are rotated by 180 degrees to drive the arm driving rotating wheel 9 to make the arm connecting shaft 5 rotate by 30 degrees, and the arm connecting shaft 5 rotates again to store force for the arm force storage disc spring 8, so that the two simulation arms 6 are lowered, and at this time the arm driving motor 10 is powered off and in a static state, and the one-way nature of the arm driving one-way bearing 30 is still used to block the output shaft of the arm driving motor 10, so that the arm driving rotating wheel 9 is pressed against the arm driving rod 7, so that the arm force storage disc spring 8 is in the force storage state, at this time the intelligent simulation combat training robot enters the intelligent interactive defense mode;

[0035] When the eye sensor 4 transmits images to the main control board, the main control board detects that the left and right sides are about to be attacked, and controls the corresponding side arm driving motor 10 to rotate once and stop quickly, so that the arm driving rotating wheel 9 is no longer pressed against the arm driving rod 7, so that the arm force storage disc spring 8 releases the force storage state, and the corresponding side simulation arm 6 is instantly lifted through the arm connecting shaft 5, so as to prevent the upcoming attack on that side, when the main control board detects that the attack stops, the arm driving motor 10 is rotated by 180 degrees again, so that the arm force storage disc spring 8 enters the force storage state again, and the simulation arm 6 enters the lowered state again, at the same time, the arm driving motor 10 is powered off and in a static state, and the one-way nature of the arm driving one-way bearing 30 is used to block the output shaft of the arm driving motor 10, and waits for the next attack to make a quick defense action;

[0036]

[0037] ​When the main control board detects that the upcoming attack also includes a frontal attack, for example, when the main control board detects that the upper body transmission box 1 is about to be attacked from the front and left side, the main control board controls the left side simulated arm 6 to be lifted up, at the same time, the waist transmission motor 12 drives the waist transmission sprocket 13 to rotate, and through the waist transmission chain 16, the transmission sprocket 15 inside the waist transmission converter 14 is driven to rotate, so that the transmission shaft 17 slides to the left inside the simulated leg 18, at the same time, the rotation of the waist transmission sprocket 13 also drives the upper body transmission chain 20 to transmit, so that the upper body transmission chain 20 pulls the upper body transmission box 1 to be inclined to the right, when the main control board detects that the attack stops, the waist transmission motor 12 rotates to reset the upper body transmission chain 20, so that the upper body transmission box 1 restores the straight expansion sleeve to meet the next attack.

[0038] When the main control board detects that the upper body transmission box 1 is about to be attacked from the front and right side, the main control board controls the right side simulated arm 6 to be lifted up, at the same time, the waist transmission motor 12 drives the waist transmission sprocket 13 to rotate, and through the waist transmission chain 16, the transmission sprocket 15 inside the waist transmission converter 14 is driven to rotate, so that the transmission shaft 17 slides to the right inside the simulated leg 18, at the same time, the rotation of the waist transmission sprocket 13 also drives the upper body transmission chain 20 to transmit, so that the upper body transmission chain 20 pulls the upper body transmission box 1 to be inclined to the left, when the main control board detects that the attack stops, the waist transmission motor 12 rotates to reset the upper body transmission chain 20, so that the upper body transmission box 1 restores the straight expansion sleeve to meet the next attack.

[0039] The initial state of the intelligent simulation combat training robot is a straight mode, when starting the training mode and the main control board detects that a frontal attack is about to be received, the backward driving motor 26 drives the motor sliding shaft 27 to move forward, that is, to move in the direction of the front end connecting wheel 25, so that the front end backward wheel 29 lifts up the front end connecting wheel 25, at the same time, the other end of the motor sliding shaft 27 drives the rear end connecting wheel 28 and the bottom of the rear end connecting spring 23 to move forward, at this time, the rear end connecting spring 23 is bent and the rear end of the base support 21 is pressed down, while the base connecting spring 22 is stretched and bent because the front end connecting wheel 25 is lifted up, so that the front end of the base support 21 is lifted up, thereby making the intelligent simulation combat training robot enter a backward state when being hit, and after the main control board detects that the intelligent simulation combat training robot has backwarded to a preset angle, the backward driving motor 26 reverses to make the intelligent simulation combat training robot restore the straight state to meet the next attack.
